Specifically, the dual head pump includes a driving motor 2121, and a first pump body 2122 and a second pump body 2123 provided on both sides of the driving motor 2121. The first pump body 2122 is mounted, for example, on a first side of the drive motor 2121, for example, the left side as viewed in fig. 3, for pumping the first liquid. A second pump body 2123 is mounted, for example, on a second side of the drive motor 2121, for example, the right side as viewed in fig. 3, for pumping a second liquid.

In the above embodiment, the first pump body and the second pump body are respectively located at two sides of the driving motor, and both are peristaltic pumps, for example. In other embodiments, the first pump body and the second pump body may be located on the same side of the driving motor, and other pumping devices may be used for the first pump body and the second pump body, for example, electromagnetic pump, diaphragm pump, gear pump, screw pump, vane pump, water ring pump, and the two may be the same or different.

Fig. 4 is a schematic structural diagram of a mixing pipeline according to some embodiments of the present disclosure. As shown in fig. 1 to 4, the liquid supply line in the cleaning apparatus 20 includes a mixing line 214, where the mixing line 214 is also disposed in the cleaning base 21, for example, the mixing line 214 includes a first inlet 2141, a second inlet 2142, and a mixed liquid outlet 2143, and is used to mix the liquid entering the first inlet 2141 and the second inlet 2142 to generate and output a mixed liquid, where the mixed liquid may be the first liquid or the second liquid entering the first pump 2122 or the second pump 2123, or the cleaning liquid distributed onto the cleaning roller 211 and/or the surface to be cleaned by the liquid distributor, where the mixed liquid outlet 2143 is the cleaning liquid outlet.

In some embodiments, as shown in fig. 3 and 4, the first pump body 2122 includes a first pump inlet 21221 and a first pump outlet 21222. The first pump inlet 21221 is connected to the clean water tank 26 via a clean water line and the first pump outlet 21222 is connected to the mixing line 214 via a transfer line. The first pump 2122 pumps the clean water in the clean water tank 26 into the mixing pipe 214 under the driving of the driving motor 2121. The first pump body 2122 is, for example, a peristaltic pump, and can pump clean water uniformly. The second pump body 2123 includes a second pump inlet 21231 and a second pump outlet 21232. The second pump inlet 21231 is connected to the cleaning agent tank 213 via a cleaning agent line, and the second pump outlet 21232 is connected to a mixing line 214 described later via a transfer line. The second pump body 2123 pumps the cleaning agent in the cleaning agent tank 213 into the mixing line 214 under the drive of the drive motor 2121. The second pump body 2123 is, for example, a peristaltic pump, and pumps the cleaning agent uniformly.

As shown in fig. 4, mixing tube 214 includes a first inlet 2141, a second inlet 2142, and a mixed liquor outlet 2143. The first inlet 2141 communicates with the first pump outlet 21222 of the first pump body 2122 via a transfer line, and the first liquid enters the mixing line 214 from the first inlet 2141 under the influence of the first pump body 2122. The second inlet 2142 communicates with the second pump outlet 21232 of the second pump body 2123, and the second liquid enters the mixing line 214 from the second inlet 2142 under the influence of the second pump body 2123. The first liquid and the second liquid are mixed into a cleaning liquid in the mixing pipe 214, and then output from the mixed liquid outlet 2143. The mixed liquid outlet 2143 communicates, for example, through a transfer line to a liquid distribution port near the cleaning roller 211, where cleaning liquid is dispensed onto the cleaning roller 211 and/or the surface to be cleaned to perform wet cleaning.

In some embodiments, as shown in fig. 3 and 4, the first pump body 2122 further includes a first pump inlet 21221 and a first pump outlet 21222, the second pump body 2123 further includes a second pump inlet 21231 and a second pump outlet 21232, the second pump inlet 21231 is connected to the cleaner tank 213 via a cleaner line, and the second pump outlet 21232 is connected to the mixing line 214 via a transfer line. The mixing line 214 includes a first inlet 2141, a second inlet 2142, and a mixed liquor outlet 2143. The second inlet 2142 is connected to the second pump outlet 21232 by a transfer line, the first inlet 2141 is connected to the clean water tank 26 by a clean water line, the mixed liquor outlet 2143 is connected to said first pump inlet 21221, and the first pump outlet 21222 is connected to a cloth port near the cleaning roller 211, for example by a transfer line. The second pump 2123 pumps the cleaning agent from the cleaning agent tank 213 and into the mixing line 214 to mix with the cleaning water, and the mixed cleaning agent is pumped by the first pump 2122 and distributed to the cleaning roller 211 and/or the surface to be cleaned to perform wet cleaning. By advancing the mixing process to the inlet of the pump body, the problem that the solution of mixing after the liquid is output by the two pump bodies causes clear water to enter the cleaner box due to capillary effect is avoided.

In some embodiments, as shown in fig. 4, the mixing pipe 214 includes a main pipe 2144 and a branch pipe 2145, wherein the pipe diameter of the branch pipe 2145 is smaller than the pipe diameter of the main pipe 2144. The first inlet 2141 and the mixed liquid outlet 2143 are provided at opposite ends of the main pipe 2144, respectively, and the liquid entering from the first inlet 2141 flows along the main pipe 2144 toward the mixed liquid outlet 2143. In some embodiments, the main conduit 2144 is, for example, linear, folded-line, curvilinear, etc.

The second inlet 2142 is provided at an end of the branch line 2145 remote from the main line 2144, the other end of the branch line 2145 being connected to the main line 2144. As shown in fig. 4, the branch line 2145 extends from the side wall of the main line 2144 in a direction inclined to the extending direction of the main line 2144, for example, the extending direction of the branch line 2145 forms an obtuse angle with the flow direction of the clean water in the main line 2144. Liquid entering from second inlet 2142 flows along branch 2145 into main 2144 by action of second pump 2123. The branch pipeline 2145 and the main pipeline 2144 are arranged obliquely, and when the liquid flows through the branch pipeline 2145 and enters the main pipeline 2144, the flowing direction of the liquid in the branch pipeline 2144 is intersected with the flowing direction of the liquid in the main pipeline 2144, so that the liquid in the branch pipeline is better mixed into the liquid in the main pipeline, and the mixed liquid is formed quickly. In other embodiments, the extending direction of the branch line 2145 and the flow direction of the liquid in the main line 2144 may be perpendicular to each other or have an acute angle therebetween.

In some embodiments, the ratio of the first liquid to the second liquid mixed in the mixing line 214 is fixed. The first pump 2122 and the second pump 2123 having uniform output are simultaneously driven by the same driving motor, and the first pump 2122 and the second pump 2123 pump the first liquid and the second liquid uniformly, respectively, thereby ensuring that the mixing ratio of the clean water and the cleaning agent in the mixing pipeline 214 is fixed. The ratio can be preset, so that a better cleaning effect can be obtained, and meanwhile, the consumption of the cleaning agent can be saved. Compared with the scheme that the user controls the proportion of the cleaning agent to the mixed clean water by himself, the scheme in the disclosure can improve the utilization rate of the cleaning agent and achieve the high-quality and stable cleaning effect.

In some embodiments, the pump fluid flow of at least one of the first pump body 2122 and the second pump body 2123 is adjustable. For example, the first pump body 2122 and/or the second pump body 2123 may adjust the flow rate of the pump fluid by adjusting the supply voltage, which may be the frequency, amplitude, or a combination of the two. The pump fluid flow may be a function of the supply voltage, such as a linear relationship.

In some embodiments, the pump body, i.e., the first pump body 2122 and/or the second pump body 2123, is, for example, a purchasing device, whose rated supply voltage adjustment range is predetermined, and the pump flow adjustable range is also predetermined. When the required flow of liquid supply is positioned in the adjusting range of the pump liquid flow of the pump body, the pump liquid flow of the body can be adjusted by adjusting the power supply voltage so as to meet the required flow of liquid supply.

In some embodiments, in some working modes, when the required flow rate of the liquid supply is not in the adjusting range of the pump liquid flow rate of the pump body and is lower than the minimum pump liquid flow rate of the pump body, the pump body interval working strategy can be adopted to meet the required flow rate of the liquid supply, namely the pump body interval pump liquid is controlled, and particularly the intermittent working of the pump can be realized by powering on or powering off the pump body, so that the average flow rate in a certain time meets the required flow rate of the liquid supply. For example, the required flow rate of the liquid supply is 1m l/s, but the minimum pumping flow rate which can be adjusted when the pump body works is 2m l/s, and after the pump is adjusted to the minimum flow rate value, the average flow rate value is 1m l/s within a period of 2s by adopting a spacing water pumping strategy of starting for 1s to stop for 1s, so that the required flow rate of the liquid supply is met.

In some embodiments, as shown in fig. 1-4, the dual head pump 212 is disposed in the cleaning base 21. Specifically, the cleaner tank 213 is provided in the cleaning base 21, and the double-ended pump 212 is provided between the cleaner tank 213 and the bottom surface of the cleaning base 21, the cleaner tank substantially covering the double-ended pump 212.

Fig. 5 is a schematic view of a partial structure of a cleaning body according to some embodiments of the present disclosure, fig. 6 is a schematic view of a cleaning water tank according to some embodiments of the present disclosure, and fig. 7 is a schematic view of a cleaning water tank according to some embodiments of the present disclosure. The clear water tank shown in fig. 7 has a different view angle from the clear water tank shown in fig. 6.

In some embodiments, as shown in fig. 1 to 7, the cleaning apparatus 20 includes an apparatus body 22 pivotally connected to a cleaning base 21, and the two are, for example, universally pivotally connected. The device body 22 has a mounting groove 221, the clean water tank 26 is detachably mounted in the mounting groove 221, the mounting groove 221 has a mounting surface 222, and a first clean water interface 2221 and at least one first positioning member 2222 are disposed on the mounting surface 222. The first clean water interface 2221 serves as a water inlet for a clean water delivery line within the cleaning apparatus 20, which is a line for delivering clean water, at least forming part of a liquid supply line.

The clean water tank 26 has an interface surface 261, and the interface surface 261 corresponds to the mounting surface 222 of the mounting groove 221. For example, when the clean water tank 26 is mounted into the mounting groove 221, the mounting surface 222 substantially conforms to the interface surface 261.

In some embodiments, as shown in fig. 1 to 7, the interface 261 is provided with a second clean water interface 2611 and at least one second positioning member 2612, and the second clean water interface 2611 is a water outlet of the clean water tank 26. When the clean water tank 26 is mounted in the mounting groove 221, the first clean water connector 2221 is matched and abutted with the second clean water connector 2611 so that the clean water conveying pipeline in the device body 22 is connected with the water outlet of the clean water tank 26, and the first positioning piece 2222 is matched and abutted with the second positioning piece 2612 so that the clean water tank 26 is stably mounted in the mounting groove 221, and the clean water tank 26 is prevented from shaking relative to the cleaning body 22. And the process of mating the first positioning member 2222 with the second positioning member 2612 can assist in quickly locating the installation position of the clean water tank 26.

In some examples, one of the first clear water interface 2221 and the second clear water interface 2611 is a clear water connector, and the other is a clear water interface slot. For example, as shown in fig. 1-7, the first clear water interface 2221 is a clear water connector that extends from the mounting surface 222 away from the mounting surface 222, e.g., from the mounting surface 222 in a direction substantially perpendicular to the mounting surface 222 away from the mounting surface 222. The second clean water connection 2611 is a clean water connection tank, and is arranged on the connection surface 261, and is recessed from the connection surface 261 towards the interior of the clean water tank 26, and an outlet of the clean water tank 26 is arranged on the tank bottom of the clean water connection tank, for example. The clear water connector and the clear water interface slot are matched in shape to size, and when the clear water tank 26 is installed in the installation slot 221, the clear water connector is inserted into the clear water interface slot, and the clear water connector and the clear water interface slot are matched and butted.

In some embodiments, one of the first and second positioning members 2222 and 2612 is a positioning protrusion, and the other is a positioning groove. For example, as shown in fig. 1-7, the first positioning member 2222 is, for example, a positioning protrusion that extends away from the mounting surface 222, for example, extends away from the mounting surface 222 in a direction substantially perpendicular to the mounting surface 222. The second positioning member 2612 is, for example, a positioning groove, and is provided on the interface surface 261, and is recessed from the interface surface 261 toward the inside of the clean water tank 26. The positioning protrusion and the positioning groove are matched in shape to size, and when the clean water tank 26 is mounted in the mounting groove 221, the positioning protrusion is inserted into the positioning groove, and the positioning protrusion and the positioning groove are matched and butted.

In some embodiments, the number of the first positioning elements 2222 and the second positioning elements 2612 may be 1 or more, which are in one-to-one correspondence.

In some embodiments, the number of the first positioning members 2222 is, for example, 2, and two first positioning members 2222 are respectively disposed at two sides of the first clean water interface member 2221, for example, the two first positioning members 2222 are disposed symmetrically with respect to the center of the first clean water interface member 2221. In a specific example, the mounting surface 222 is, for example, a quadrilateral, and the two first positioning members 2222 are located on a diagonal line of the mounting surface 222. Correspondingly, the number of the second positioning members 2612 is also 2, for example, two second positioning members 2612 are respectively disposed on two sides of the second clear water interface member 2611, for example, two second positioning members 2612 are disposed symmetrically with respect to the center of the second clear water interface member 2611. In a specific example, the interface surface 261 is, for example, a quadrilateral and the two second positioning members 2612 are located on a diagonal of the interface surface. With this design, the mounting and positioning of the clean water tank 26 and the mounting groove 221 can be facilitated, and the clean water tank 26 mounted in the mounting groove 221 is prevented from shaking with respect to the apparatus body 22.

In some embodiments, the first clear water interface 2221 is also located on the diagonal of the mounting face 222, and correspondingly the second clear water interface 2611 is also located on the diagonal of the interface face 261.

In some embodiments, as shown in fig. 1-7, the water outlet of the clean water tank 26 is disposed proximate to the top 262 of the clean water tank 26, and in particular, the distance between the water outlet of the clean water tank 26 and the top 262 of the clean water tank is less than the distance between the water outlet of the clean water tank and the bottom 263 of the clean water tank, e.g., the ratio of the distance between the water outlet of the clean water tank 26 and the top 262 of the clean water tank to the distance between the water outlet of the clean water tank and the bottom 263 of the clean water tank is less than 1/2, with this arrangement, the clean water tank 26 is not prone to water leakage.

In some embodiments, the clean water tank 26 further includes an intake choke valve 264, the intake choke valve 264 being disposed at the top 262 of the clean water tank 26. The intake choke valve 264 is used to balance the air pressure of the clean water tank 26 with the outside air pressure. The intake choke valve 264 is configured to allow gas into the clean water tank but to prevent liquid, such as water, from escaping the clean water tank. Since the water outlet of the clean water tank 26 is disposed near the top 262 of the clean water tank, the water in the clean water tank 26 needs to be extracted from the clean water tank by external force, the air pressure in the clean water tank 26 is reduced in a manner that is unfavorable for the extraction of clean water in the clean water tank 26 if the air pressure in the clean water tank 26 is continuously reduced, and at this time, the clean water tank can be communicated with the outside so that the outside air enters the clean water tank, so that the clean water tank 26 maintains stable air pressure, and the clean water can be usually realized by providing a through hole in the clean water tank, but the clean water in the clean water tank also leaks from the through hole by adopting the through hole. Based on this, the intake choke valve 264 is used to balance the air pressure between the clean water tank 26 and the outside, so that the clean water is pumped normally without leakage.

In some embodiments, the intake block valve 264 comprises a silicone cross valve that is simple in construction, low in cost, and has excellent air-permeable block properties.

In some embodiments, a float indicator, such as a float, may also be provided in the clear water tank 26, configured to detect the amount of water in the clear water tank. The floating ball is arranged at the inner bottom surface of the clean water tank, and triggers the alarm device to send out an alarm signal when the water quantity of the clean water tank is lower than a preset value so as to remind a user to fill clean water.

In some embodiments, a water pumping pipe is disposed in the clean water tank 26, one end of the water pumping pipe is connected to the water outlet of the clean water tank, and the other end of the water pumping pipe is disposed at the inner bottom surface of the clean water tank 26. To ensure that the water of the fresh water tank can be pumped out basically.
